How do I loop this data?

% Degrees of Freedom;

% Free

Bl=1;

BR=hd+1;

TL=(hd+1)*(vd+1)-hd;

TR=(hd+1)*(vd+1);

freedof=[Bl,BR,TL,TR];

for i=Bl+1:BR-1;

   freedof(i)=[3i-2 3i-1 3i];

end

for i = BR+1:1:TL-1

end

for i=TL+1:1:TR-1

end

error comes back as :

In an assignment A(I) = B, the number of elements in B and I must be the same.

Error in FDM>readinputdata (line 80) freedof(i)=[3i-2 3i-1 3i];

Error in FDM (line 9) [ndof,nnodes,connectivity,q,freedof,P,fixdof,Uf,axialunits,lengthunits]=readinputdata; >>

from what i see, without running it, is that in the freedof(i)=[3i-2 3i-1 3i]; it is trying to assign all 3 3i-2 3i-1 3i] into the index freedof(i) which is 1x1. to get around this you can go

 freedof(i,:)=[3i-2 3i-1 3i];

one other thing i see is that you define freedof right before the for loop as a 1x4 matrix. however in the forloop freedof is 1x3. what are you looking for the other number?
